there is no question Picco uses a harder piston then a GO does...I am not knocking the GO, but its piston life is not as long as a Picco's is....I use the same fuels with both motors, so thats not a variable in my evaluation.......as well I will take a forged piston over hypereutectic any day..
Also I am not knocking the GO engines, I run them myself and have modified quite a few with great results... but we are definitely finding the Picco's will hold the piston edge longer then a Go will..
has anyone here run Picco and Go onthe same fuel ? and if so what did you find ?
